本研究旨在探討調和式熱情、強迫式熱情、流暢體驗變數間之關係，並探討知覺風險在上述變數關係間扮演之調節角色。以登山遊憩活動參與者為研究對象進行問卷調查，獲得有效問卷回收584份，以偏最小平方法進行統計分析。研究結果顯示：調和式熱情與強迫式熱情同時會正向影響流暢體驗（流暢、高峰經驗）。登山參與者知覺風險在二元熱情（調和式、強迫式）對流暢體驗中之流暢構面關係扮演調節角色。建議遊憩參與者先藉以本研究量表分析熱情偏向，選擇契合自身技能之遊憩活動以利正向遊憩體驗，並藉以參與過程建立休閒社交圈交流學習提升活動知識與技巧，另建議政府、民間業者等規劃多元戶外遊憩環境使遊憩參與者豐富遊憩體驗。

This study discusses the variable relationship among harmonious passion, obsessive passion, and flow experience and examines the moderating role of perceived risk among the variables. The targets of this study were mountaineering participants. Partial least squares (PLS) structural equation modeling was applied to analyze the collected data from 584 valid questionnaires. The results showed that the harmonious or obsessive passion of mountaineering participants had a positive influence on flow experience, flow, and peak experience. The perceived risk of the mountaineering participants had a moderating effect on the harmonious and obsessive passion toward the flow structure of flow experience. The findings suggest that recreation participants should identify their passion tendency using the scale in the study, choose fit recreation activities to experience recreation activities positively, and build leisure circles to increase their activity knowledge and skills. The government and private industries should plan various outdoor recreation environments to provide participants with more abundant recreation experiences.
